IME.'IROIEED DIE DFOR FORMING- T-BOLTS FOR WHIFFLBTREE.

The Schedule referred to in these Letters Patent and making part of the'same.

To all whom it may concern:

Be it knownthat I, F. B. MORSE, of Plantsville, in the county ofHartford and State of Connecticut, have invented a new Improvement inDies for Forging Whittletree-Bolts; and I do hereby declare thefollowing, when taken in connection with the accompanyingr drawings andthe letters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings constitute part of thisspecification, and representin- Figure 1 the upper die inverted Figure2, the lower die;

Figure 3, the blank preparatory to placing in the die;

Figure 4, a side view; and i Figure 5, a top view of the bolt as itcomes from the die.

This invent-ion relates to dies for forging the whifetree-bolt patentedto me, and dated October 26, 1869, the object being to form the pointsor pins upon the under side of the head, and still retain the perfectform of `the outer surface, this class of bolts, before my invention,having been made by bending the pointed ends down, so as to turn intothe wood, de tracting materially from .the graceful appearance andfinish of the bolt-head.

The lower die A (sce fig. 2) is formed with a flat upper surface,Aperforated at B, for the intr'oduction of l the bolt, and at a arecesses are formed, for the projections upon the under side of thehead.

The upper'die G (see iig. 1) is formed with a fiat surface, in which acavity, D, is made, corresponding to the exterior of the head of thebolt. y

The blank, seen in fig. 3, is prepared by drawing the spindle E of thebolt into the desired form, with the requisite amount of metal, in roughshape, to form the head, as seen in tig. 3. 'lhe head is then heated,and set upon the lower die. The spindle E, passing into the perforationB, holds the blank in the required position. -Then the upper die O isdropped or forced 4onto the head, the cavity D forming the uppersurface, as seen in figs. 4 and 5, and the metal, entering th'e recessesa a in the lower die, forms projections, ff, upon theunder side, andthrows the surplus met-al into actin around the edge of the head, whichis afterward trimmed ofi'in the usual manner for trimming forgings.

I claim as my invention- The dies, constructed as herein described, forforging whitiietree-bolts. v

F. B. MORSE.
